"Applied Materials' code APP appears in Marriott corporate code lists but has minimal community discussion. A FlyerTalk comment notes that some codes "are old and may not be valid, and some may require ID of some sort," and that rates are "widely offered and hard to check ID" particularly when extended to company retirees. Applied Materials is a major Silicon Valley semiconductor equipment company; Bay Area hotel density reduces the novelty of tech company codes in that market."

"I do security for a Marriott Hotel in Miami and when it comes to guests being disrespectful like cursing, and/or getting physical with employees or furniture, the front desk calls security. We get there and we gives two warnings. If they continue to curse or be any type of physical, we throw they ass out the hotel as an eviction. We dont play that shit here in Miami."

"I don't do mobile check-in if I'm wanting to upgrade. I check the app before I go in to see if any suites are available to book during the duration of my stay. If there is I just say "Would it be possible to get upgraded to an available suite with my platinum benefit?". Of course this is typically at the hotel that I stay in about once a month for 3 day at a time for work. The front desk pretty much knows me and know that I am fairly low maintenance."
